I recently had someone email me that had purchased our 8 day course (we sell as an illustrated booklet for those that are in a hurry to make a decision).
He asked this question: "How does your system "tune"? I plan on purchasing your kit with tuner, but don't understand what I am tuning."
That's a great question. I figured others might have the same one, so this is how I answered it:
The “tuners” we provide, don't directly affect the flow of fuel, we rely on the massive work of the engineers who programmed the engines with specific fuel maps, based on the engines needs, to do that.
All engines with computers (ECM's) use sensors to gather data and send that to the ECM. The ECM then chooses the proper fuel map, based on that information, which is constantly changing. Most "TUNERS" try to inject their own programs to help the engine get more horsepower or economy, but many times the ECM will override their attempts (especially when it comes to gas savings!)
So our tuners bypass the programming entirely, and "hijack" the signal before it gets to the ECM. We actually route the signals coming from the O2 sensors and MAF/MAP sensors, before they reach the car computer (ECM). While it seems “that is not enough”, the sensors are quite sensitive to changes internally in the engine, and just a few millivolts of change affects WHICH fuel map the ECM decides to use, which determines how much fuel to inject. In other words, we are not trying to work against the engineering software of the car, we are simply changing the inputs that determine how much fuel is used. We can adjust the MAF (in most cars) to actually cause the engine to stumble because the fuel is leaned out by the ECM, based on those signals. So while we are only adjusting or tuning the signals by using a voltmeter, we are leveraging the car computer to do the rest of the work.
Does that make sense? Obviously, it is much more complex than that, but essentially, computers are only as smart as the data that is input into them. We make sure they get the right data to lean out the fuel in an unconventional way.
Hope that helps...
